Weegy: Mr. Jones, the science teacher, tells his students that energy cannot be created; it must be captured from the environment. He is talking about the first law of thermodynamics. J_ME|Points 35|

User: According to the second law of thermodynamics, heat energy released by an organism is _____.
gone forever
used by another animal
released into the environment and unusable
absorbed by plants for photosynthesis

User: Which of the following is an example of energy changing from one form to another?

User: A food chain or food web can provide good information like _____.
the flow of energy in an ecosystem
the eating patterns of organisms
the types of food that are best for you to eat
how much energy is transferred from one organism to another

User: Most energy in an ecosystem comes originally from _____.
plants
primary consumers
the Sun
the soil

Weegy: You are a tertiary consumer if you feed on secondary consumers.sharpies|Points 7198|

User: You are a _____ consumer if you feed on secondary consumers.
producing
primary
secondary
tertiary

Weegy: You are a tertiary consumer if you feed on secondary consumers.sharpies|Points 7208|

User: About how much energy is transferred between a producer and primary consumer?
90% of the original energy from the Sun is transferred
10% of the original energy from the Sun is transferred
10% of the plant's energy is transferred
0.9% of the plant's energy is transferred

Weegy: Only about 10% of the energy from the producer is passed on to the consumer. Koolsum|Points 1139|

User: A plant absorbs energy from the sun. Where does the energy go from there?
All of the energy is transferred to primary consumers.
All of the energy is used by the plant.
All of the energy is released as heat energy.
Some of the energy is stored in the plant's tissues and the rest is released as heat energy

User: Life cycles recycle matter and help to create balance on Earth because _____.
Living organisms are dependent on other living organisms to survive.
Producers make their own food. Consumers gain energy from producers. Decomposers break down dead matter into essential nutrients that are then reused by producers.
Producers gain energy from the sun. Consumers gain energy from producers. Decomposers gain energy from dead consumers and recycle it back to producers.

Weegy: The answer is the carbon cycle. Or the answer to the paragraph is A. sharpies|Points 7208|

User: During spring, when Earl's crops were plentiful, he noticed an increased number of rabbits. At night, he also heard an increased number of howls from the coyotes. What do you think will happen when winter comes around and the crops die out?
The plants in a nearby forest would decrease to sustain the rabbit population.
Coyote population will increase from the increased number of rabbits.
Both the rabbit and coyote population could decrease because the original food supply decreased.

User: Ecosystems usually become balanced by natural controls, including natural selection. A balanced ecosystem is one in which _____.
the first organism on the food chain must outnumber the subsequent organisms on the food chain.
there are an equal number of organisms at all levels of the food chain.
the last organism on the food chain must outnumber the first organism on the food chain.
